True heroes never say die, and that's an idea that certainly rings true for Batman, the DC Comics icon who celebrates his 75th anniversary this year.

Unlike many of his comic book counterparts, Batman is not immortal or gifted with extravagant superpowers - he is just a man, albeit one with a hefty bank balance and a determination to rid his home Gotham City of crime and corruption.

Since his creation in 1939 by Bob Kane and Bill Finger, he's traversed every form of entertainment imaginable; be it comics, TV, film, music or video games, Batman has left his mark on pop culture in a big way.

Why has Batman endured for decades? Digital Spy visited London's Orbital Comics to speak to Chris Thompson about the lasting appeal of the Dark Knight. Watch us go through the history of the Caped Crusader - from Kane to Frank Miller, Tim Burton to Christopher Nolan - in the video above.
